Volvo Construction Equipment (Volvo CE) president and chief executive Pat Olney said demand for construction equipment in North America could jump by a quarter in 2012, after revealing the company posted a 111% increase in like-for-like first quarter year sales. Olney said Volvo CE’s strong Q1 2012, and improved overall construction equipment trading in the US and Canada, had re-emphasised the company’s belief in a sustained North American market recovery.
